The Seven Wonders of the Ancient World

This list was established around 200 B.C. by various authors. We don't know who was the first one to draw up such a list, but nowadays, Philo of Byzantium's list is the most commonly accepted ;

• The Great Pyramid of Giza (the only one that still remains)
• The Hanging Gardens of Babylon
• The Artemis temple at Ephesus
  
• the Statue of Zeus at Olympia
• The Mausoleum at Halicarnassus
  
• The Colossus of Rhodes
  
• The Lighthouse at Alexandria

In the text, they are referred to as "sights", or literally "things to be seen" ; the purpose was indeed to give Greek tourists a summary of the main places of interest in the world (for them, the Mediterranean Sea).
